Run it along the chain stay, under the BB shell, then tape it to down tube, full length. It would probably be more aero to tape it to the top of the down tube, then spiral up the rear brake housing a ways, then branch off to the stem.

is it possible to cut and solder the wire back together and heat shrink it? Id like to be able to run it internally w/ the fd or rd wires somehow..

I'm sure you can - but when the harness runs ~$70, I wouldn't want to be the first to try.

My friend tried that and it doesn't work very reliably. The signal kept dropping out, especially in damp or rainy conditions. It was bad enough that he ended up replacing it. Even using a high quality soldering iron at a university EE lab it didn't work well.

On my TT bike, I run it underneath the top tube, transfer to the brake cable, to the back of the seat stays, and have the receiver on the back of the seat stays facing backwards.

I cut one of mine, ran it through the frame and soldered it. What a pain in the ass. To top it off, I ended up cutting it on both ends as I couldn't fish it through from bottom to top, as I originally wanted. There are 4 tiny wires in there and you really need to heat shrink each one, then heat shrink the whole thing. Of course, you're also soldering with the wires sticking out of a frame which is harder than doing it on a work bench.

Mine worked reliably when it was done, I just don't think I'll go through that much work again.

the "under the BB shell and up the bottom of the downtube" can get pretty messy pretty fast.

I suggest:
Get a hold of some white electrical tape and run it up the trailing edge of your downtube. I've done that on my Soloist with favorable results.

I would think cutting and soldering the wires for an extremely low power radio receiver would alter the impedance just enough to mess with the data. Just a theory though.

I agree. This is the slickest way that I have found to route it on a TT bike. Get some electrical tape that is the same color as the bottom of the top tube an nobody will know that it is there. I've heard of several people cutting the SRM cable and routing it internally, but not the PT cable. If you did decide to cut the cable you could drill out a hole in your extensions and route your shifter and PT cable out the back and down through the internal routing on the down or top tube. That would be really slick.

You could use window sealing tape. It is essentially a thinner version of clear chainstay protector. It removes safely.

Heh heh.
I picked up a brand new wired SL on an open pro last week, fitted it christmas eve and it doesn't look too bad at all.
